HELICONIDH—ITHOMIA. 
ITHOMIA SYNNOVA. 126. 
Upprrsipe. Female black. Anterior wing with nearly all the cell, and a line between it, 
and the anal angle orange. A large semi-transparent white spot beyond the middle. Posterior 
wing with the outer half, except the margin, orange. 
Unpersrpe as above, except that there are two small white spots at the apex of the pos- 
terior wing. 
Expan. 133 in. Hab. Amazon.

ITHOMIA DUESSA. 137. 
Uprersipr. Female black. Anterior wing with the base rufous. A large central 
irregular spot of light yellow, marked with a black spot. ‘Iwo small white spots at the apex. 
Posterior wing rufous; the apex and two irregular bands, which spring from it and partly cross 
the wing, together with the outer margin, black. 
Unpnrstpe as above, except that the base of the anterior wing is black, with two rufous 
lines only ; that the demi-bands of the posterior wing are continued to the inner margin, broken 
into spots as they approach it, and that both wings have a submarginal row of white spots.

ITHOMIA OULITA. 138. 
Uprrrsipx. Male. Anterior wing pale yellow, semi-transparent, clouded near the base 
and outer margin. The nervure, which closes the cell and the ends of the other nervures as they 
approach the outer margin, black. The margins broadly black. Posterior wing orange, except 
near the costal margin, where it is nearly white. Outer margin broadly black, narrow towards 
the anal angle. Both wings with a submarginal row of white spots. 
UnpersipE does not differ, except that there are two additional white spots near the anal 
angle of the posterior wing.

ITHOMIA NORELLA. 189. 
Urrrrsips. Male black. Anterior wing black from the base to the middle; at the 
middle a group of light yellow spots; one single, within the cell; one on the costal margin, 
forming part of a curved unequal band which crosses the wing. Beyond the band transparent 
grey ; the nervures and margins black. Posterior wing orange, with a black spot at the end of 
the cell; the apex and outer margin to its middle black, with a row of white spots. 
UNDERSIDE as above. 
Expan. 2,% in. Hab. Cuenca.

I quite expected that this and the preceding would prove to be sexes of the same species. They are, however, 
both males; and, though very much alike, differ in the position of the nervures of both wings. In this species the 
second branch from the subcostal nervure rises at the end of the cell; in I. Oulita the same branch is considerably 
beyond it. ‘The disco-cellular neryules of the posterior wing also differ.
